Abstract
To reduce coke production during low temperature coal tar hydrocracking in supercritical gasoline, a lump kinetic model was derived on the basis of catalytic cracking reaction mechanism. Lumps were defined by different reaction properties. Reaction rate constants, indexes of hydrogen to coal tar ratio, indexes of gasoline to coal tar ratio, activation energies, and pre-exponential factors were estimated according to the previous experimental data. The results_x000D_
show that the proposed model could not only predict the product yields successfully, but also provide more information which was useful for any attempts to reduce the coke content and promote the conversion of coal tar to light oils.
